FTTx

In FTTx (Fiber To The x, referring to Fiber-to-the-Home/Building/Curb, etc.) applications, PON (Passive Optical Network) is commonly used because it offers an efficient, cost-effective, and scalable solution for delivering high-speed internet and other services to end users.

PON uses a point-to-multipoint architecture. A single fiber from the OLT (Optical Line Terminal) at the provider's central office is passively split (using optical splitters) to serve multiple customers ONU/ONT (Optical Network Unit/Terminal).

PON is standardized by bodies like ITU-T and IEEE (e.g., GPON, XG-PON, EPON, 10G EPON), ensuring interoperability and long-term support.

The following are fiber optic transceiver modules that can be used in FTTx architecture:
